  • a base plate portion 13 is formed integrally to be protruded from an upper surface of an upper lid 12 formed integrally with the inner cylinder 9.
  • An upper surface of the base plate portion 13 acts as an abutting face 13A where a steering wheel is to be fixed.
  • a part of a circumferential portion is removed so that a press face (canceller portion) 14 to be erected perpendicularly to the upper surface in a radial direction of the inner cylinder 9 is formed in the base plate portion 13.
  • the canceller portion 14 is rotated integrally with the inner cylinder 9 through return rotation of the steering, thereby abutting on a return portion (cancel cam) 15 of a turn signal cancel mechanism. Consequently, the turn signal lever 6 is returned to a neutral position.
  • a signal transmitting device 21 for a steering shown in Fig. 5 an inner cylinder 23 is rotatably attached to an outer cylinder 22 and a cable which is not shown is accommodated spirally in an annular space formed therein.
  • a cancel cam 24 is protruded integrally from an outer peripheral surface of the inner cylinder 23.
  • the outer cylinder 22 is screwed to the column side by inserting a screw through a hole 25A formed in a fixing portion 25.
  • a lever unit such as a turn signal lever is attached to the signal transmitting device 21 for a steering in a direction of an arrow A, for example.
  • the cancel cam 24 is rotated together with the steering in a direction of an arrow B (or a reverse direction to the B direction) in the drawing with respect to a return portion (cancel portion) provided in a lever unit. Consequently, the return portion is repelled with the cancel cam 24 to return the lever unit to a neutral position.
  • the invention is directed to a signal transmitting device for a steering including:
  • the side wall erected on the body portion and the flange portion formed on the peripheral surface of the upper case function as dust prevention walls and can prevent refuse from entering a passage of the cancel cam.
  • the side wall erected on the body portion and the flange portion formed on the peripheral surface of the upper case function as dust prevention walls and can prevent refuse from entering a passage of the cancel cam.
  • a mechanical strength of the upper case can be increased by the flange portion.
  • a mechanical strength of the upper case can be increased by the flange portion.
  • the height of the side wall is set to be equal to or greater than that of the position where the flange portion is formed at the upper case.
  • Fig. 1 is an exploded perspective view showing a signal transmitting device for a steering according to the embodiment
  • Fig. 2 is a front view showing the signal transmitting device for a steering according to the embodiment
  • Fig. 3 is a partially sectional side view showing the signal transmitting device for a steering.
  • a signal transmitting device 30 for a steering comprises: a body portion 31 to be fixed to the column side; an upper case 32 rotatably provided in the body portion 31; and a spiral cable 29 to be spirally accommodated in an annular internal space formed by the body portion 31 and the upper case 32.
  • the body portion 31 has a through hole 31A provided on a center thereof, through which a steering shaft (not shown) is to be inserted. Moreover, the body portion 31 has a fixing portion 33 formed integrally to be protruded toward the outside. A bolt inserting hole 33A is formed on the fixing portion 33. A bolt is inserted through the bolt inserting hole 33A and is fixed with a screw to the column side (not shown). Furthermore, a pair of fixing bracket portions 34 and 35 are protruded from an outer side surface of the body portion 31. As shown in Fig. 2, a connecting portion 37 of a turn signal lever 36 is attached between the fixing bracket portions 34 and 35.
  • a fixing bracket portion 39 to which a wiper lever unit 38 is to be attached is provided in an substantially opposite position to the fixing bracket portions 34 and 35 over the outer side surface of the body portion 31 as shown in Figs. 2 and 3.
  • a side wall 31B having a predetermined height is integrally formed as an annulus ring rising wall on an upper surface of the body portion 31 to surround a peripheral surface of the upper case 32 to be assembled.
  • a window portion 31C having a portion of the side wall 31B taken away is formed on the side wall 31B in a position where the turn signal lever 36 is to be attached.
  • a cancel portion 42 of the turn signal lever 36 which will be described below can be protruded from the same portion toward the inside of the side wall 31B.
  • the upper case 32 has a through hole 32A provided on a center thereof, through which the steering shaft is caused to penetrate.
  • a projection-shaped cancel cam 40 and a flange portion 41 for circulating over an outer peripheral surface thereof are protruded integrally from an outer peripheral surface of the upper case 32.
  • the flange portion 41 is perpendicularly protruded from the outer peripheral of the upper case 32.
  • an end face of the connecting portion 37 of the turn signal lever 36 is provided with the cancel portion 42 for being pressed to return the turn signal lever 36 into a neutral position.
  • the cancel portion 42 is urged in such a direction as to be protruded toward the outside of the end face through a spring member (not shown).
  • One end 29A of the spiral cable 29 for signal transmission which is accommodated in the signal transmitting device 30 for a steering is led from the body portion 31.
  • the end 29A is connected to the turn signal lever 36 and the wiper lever unit 38.
  • the other end 29B of the spiral cable 29 is connected to a connector 43 protruded from an upper surface of the upper case 32.
  • the connector 43 is connected to an air bag or various switches on the steering side, for example.
  • the side wall 31B surrounds the cancel cam 40 and the flange portion 41 to be accommodated therein as shown in Fig. 3.
  • a height of the side wall 31B is set to be equal to or greater than that of the position where the flange portion 41 is formed at the upper case 32. Therefore, the flange portion 41 and the side wall 31B function as dust entering prevention walls and can prevent dust from entering a passage of the cancel cam 40.
  • the dust can be prevented from entering when the signal transmitting device 30 for a steering is to be assembled or after vehicle loading. Therefore, the operation of the cancel cam 40 can be prevented from being disturbed by the refuse so that reliability of the signal transmitting device 30 for a steering can be enhanced.
  • the flange portion 41 is formed integrally with the cancel cam 40 over the peripheral surface of the upper case 32. Consequently, a mechanical strength of the cancel cam 40 can be increased. Therefore, even if a user intentionally locks the turn signal lever 36 (a load to be applied to the cancel cam 40 is lever locked), for example, it is possible to prevent the strain and deformation of the upper case 32 from being generated.
  • the body portion 31 may be formed in a part of a column, that is, a concave portion to function as the body portion may be formed on the column side and the upper case 32 may be rotatably accommodated in the concave portion.
  • the number of parts can be reduced.
  • the side wall erected on the body portion and the flange portion formed on the peripheral surface of the upper case function as the dust entering prevention walls and can prevent refuse from entering the passage of the cancel cam.
  • the side wall erected on the body portion and the flange portion formed on the peripheral surface of the upper case function as the dust entering prevention walls and can prevent refuse from entering the passage of the cancel cam.
